A skill is packaged know-how that teaches an AI assistant to do a specific job your way. Every major assistant now has them, under different names: Claude Skills and plugins, ChatGPT plugins (custom GPTs retire 11 Dec 2026), Copilot plugins for Cowork, and Gemini Skills (replacing Gems from 17 Nov 2026). Most use the same open SKILL.md format, so a skill written for one assistant often works in another. The shelf has two sides: one for business users, with what's worth trying for real work and what's worth watching, and one for builders making sites, apps and tools.
